Measurements of the cosmic background radiation
Abstract
Maps of the large scale structure (theta is greater than 6 deg) of the cosmic background radiation covering 90 percent of the sky are now available. The data show a very strong 50100 sigma (statistical error) dipole component, interpreted as being due to our motion, with a direction of alpha = 11.5 + or  0.15 hours, sigma = 5.6 + or  2.0 deg. The inferred direction of the velocity of our galaxy relative to the cosmic background radiation is alpha = 10.6 + or  0.3 hours, sigma = 2.3 + or  5 deg. This is 44 deg from the center of the Virgo cluster. After removing the dipole component, the data show a galactic signature but no apparent residual structure. An autocorrelation of the residual data, after substraction of the galactic component from a combined Berkeley (3 mm) and Princeton (12 mm) data sets, show no apparent structure from 10 to 180 deg with a rms of 0.01 mK^{2}. At 90 percent confidence level limit of .00007 is placed on a quadrupole component.
